- 18. Best Practice for java client
- 19. • HSClient is thread-safe, so you must use it as SINGLETON object in your application. • Open index is an expensive operation, so reuse an opened index id as much as possible. • IndexSession is thread-safe,so please reuse an opened IndexSession as much as possible. • Use IndexSession rather than HSClient • Use ModifyStatement to insert/update data
- 20. ModifyStatement example code ModifyStatement stmt = this.session.createStatement(); stmt.setInt(1, 0); stmt.setString(2, "dennis"); stmt.setInt(4, 27); stmt.setString(5, "2010-11-28 13:24:00"); stmt.update(keys, FindOperator.EQ);
